CLUTCH DRIVING MECHANISM.

' Application filed August 11, 1921. Serial No. 491,529.

To all whom it may concern:

Be it known that I, HENRY WEILDING, a British subject, residing at Belfast, Ireland, have invented certain new and useful Improvements in Clutch Driving Mechanism, of which the following is a specification.

This invention relates to a friction clutch driving mechanism with striking gear operated by a screw more particularly designed for the driving of spinning frames for flax and other fibre.-

It consists in the particular construction and disposition of the parts hereinafter described with reference to the accompanying drawing.

' The figure is a sectional elevation through the friction pulleys.

The driven element is constructed with a clutch member A to be attachedto the shaft C of the machine to be driven and-a driving member B (preferably with a V groove around its periphery for a rope drive) is mounted loosely on a sleeve upon which it is free to rotate. The sleeve 0 is loosely mounted on the shaft C and at its outer end over a brush 0 which fits closely or is keyed on to the shaft. The interior of'the sleeve 0 is bored out larger than the shaft C at one end forming a recess therein and a spring E is inserted which surrounds the shaft 0 and abuts at one end against the interior of the sleeve 0 and at the other end against the bush 0. The bush 0 is prevented from moving longitudinally on the shaft C, and

is held in position thereon by a screw (1 screwed into the end 'of the shaft. The tendency of the spring compressed between the sleeve and the bush is to move the sleeve 0 along the shaft. The driving member B of the clutch is held in position on the sleeve '0 by a stop washer orring I) which is secured to the sleeve 0 by a set screw or screws I) placed radially or by a grub screw or screws 5 inserted longitudinally, or both so that any movement of the sleeve 0 longitudinallyof the shaft C carries with it the clutch member B. On thestop washer or ring b a loose ring D is placed which is capable of rotary movement in' relation to the stop washer b and is fitted with trunnions or pins (Z with which arms f on a shaft]? engage.

This construction forms a strikingfgcar,

the driving clutch member B being-forced ito contactwith the driven'clutch member A by the spring E within the sleeve c, and V withdrawn from contact by the arms f on the rotation of the shaft F.

By this construction when the clutch members are out of contact there is little or no. friction against the boss of thecontinuously running driving member B, as the clearance betweenjthe stop washer. b and the flange on the screw 0: allows. the sleeve o to move the member B out of engagement with the mem her A, in which position'the member B is again in equilibrium in its bearing on the sleeve 0.

An oil passage K closed by a spring and ballvalve la is provided in the stop washer b'and sleeve 0 to lubricate thedriving' member B when running free on the sleeve, and

the ring D is lubricated by an oilpassage is.

The V driving rim of thedriving member B of the clutch is preferably bolted thereto and for it a belt rim or toothed driving rim may be substituted With a rope drive the cyclic variations due to the prime mover re damped out or absorbed in the rope giving a steady turning movement which is very desirable in certain classes of spinning.

What I claim as my inventi to protect by Letters Patent is A friction clutch driving mechanism for spinning frames and other machines comprising the combination'with a driven clutch member adapted to be affixed to a shaft, a driving clutch member free to rotate around a shaft and a sleeve upon which the latter is free. to rotate, formed with an internal recess, of a spring within the recess in the sleeve to move it and the clutch memon and desire her mounted thereon in one direction, a.

bush within the sleeve against which one endof the spring abuts and adapted to be afiiXed to the shaft,-a stop washer secured to the exterior of the sleeve to maintain the clutch member in position thereon and" a ring on the stop washer provided with trunnions' by which to move the sleeve against the pressure of the spring substantially as 7 described.
